Data falsification is a serious social problem in Japan. In the construction industry, an incident occurred two years ago in which the falsified piling data had been found for a tilting condominium building, but a definitive solution for the falsification has yet to be realized. In order to solve this problem, we developed a framework where clients/contractees, architects and contractors share construction data/information in real-time. We are commercializing our construction management system, which uses the IoT and our unique technology to make it impossible to falsify data, in order for customer satisfaction improvement and building up reliability for the construction industry.
